The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2261 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform     that combines the most stable version of the Ceph storage system with a     Ceph management platform, deployment utilities, and support services.

    Security Fix(es):

    * ceph: cephx protocol is vulnerable to replay attack (CVE-2018-1128)

    * ceph: cephx uses weak signatures (CVE-2018-1129)

    * ceph: ceph-mon does not perform authorization on OSD pool ops (CVE-2018-10861)

    For more details about the security issue(s), including the impact, a CVSS     score and other related information refer to the CVE page(s) listed in the Reference section.

    Enhancement(s):

    * Ceph OSDs now logs when they shutdown due to disk operations timing out by default. (BZ#1568897)

    * The `radosgw-admin orphans find` command can inadvertently remove data objects still in use, if followed     by another operation, such as, a `rados rm` command. Users are now warned before attempting to produce     lists of potentially orphaned objects. (BZ#1573656)

    * The 'ceph-osdomap-tool' now has a 'compact' command to perform offline compaction on an OSD's 'omap'     directory. (BZ#1574231)

    * For S3 and Swift protocols, an option to list buckets/containers in natural (partial) order has been     added. Listing containers in sorted order is canonical in both protocols, but is costly, and not required     by some client applications. The performance and workload cost of S3 and Swift bucket/container listings     is reduced for sharded buckets/containers when the `allow_unordered` extension is used. (BZ#1595374)

    * An asynchronous mechanism for executing the Ceph Object Gateway garbage collection using the `librados`     APIs has been introduced. The original garbage collection mechanism serialized all processing, and lagged     behind applications in specific workloads. Garbage collection performance has been significantly improved,     and can be tuned to specific site requirements. (BZ#1595383)

    Bug Fix(es):

    These updated ceph packages include numerous bug fixes. Space precludes     documenting all of these changes in this advisory. Users are directed to the Red Hat Ceph Storage 2.5     Release Notes for information on the most significant bug fixes for this release:

    Bug Fix(es):

    * Previously, Ceph RADOS Gateway (RGW) instances in zones configured for multi-site replication would     crash if configured to disable sync (rgw_run_sync_thread = false). Therefor, multi-site replication     environments could not start dedicated non-replication RGW instances. With this update, the     rgw_run_sync_thread option can be used to configure RGW instances that will not participate in     replication even if their zone is replicated. (BZ#1552202)

    * Previously, when increasing max_mds from 1 to 2, if the Metadata Server (MDS) daemon was in the     starting/resolve state for a long period of time, then restarting the MDS daemon lead to assert. This     caused the Ceph File System (CephFS) to be in degraded state. With this update, increasing max_mds no     longer causes CephFS to be in degraded state. (BZ#1566016)

    * Previously, the transition to containerized Ceph left some ceph-disk unit files. The files were     harmless, but appeared as failing. With this update, executing the switch-from-non-containerized-to-     containerized-ceph-daemons.yml playbook disables the ceph-disk unit files too. (BZ#1577846)

    * Previously, the entries_behind_master metric output from the rbd mirror image status CLI tool did     not always reduce to zero under synthetic workloads. This could cause a false alarm that there is an issue     with RBD mirroring replications. With this update, the metric is now updated periodically without the need     for an explicit I/O flush in the workload. (BZ#1578509)

    * Previously, when using the pool create command with expected_num_objects, placement group (PG)     directories were not pre-created at pool creation time as expected, resulting in performance drops when     filestore splitting occurred. With this update, the expected_num_objects parameter is now passed through     to filestore correctly, and PG directories for the expected number of objects are pre-created at pool     creation time. (BZ#1579039)

    * Previously, internal RADOS Gateway (RGW) multi-site sync logic behaved incorrectly when attempting to     sync containers with S3 object versioning enabled. Objects in versioning-enabled containers would fail to     sync in some scenariosfor example, when using s3cmd sync to mirror a filesystem directory. With this     update, RGW multi-site replication logic has been corrected for the known failure cases. (BZ#1580497)

    * When restarting OSD daemons, the ceph-ansible restart script goes through all the daemons by listing     the units with systemctl list-units. Under certain circumstances, the output of the command contains extra     spaces, which caused parsing and restart to fail. With this update, the underlying code has been changed     to handle the extra space.

    * Previously, the Ceph RADOS Gateway (RGW) server treated negative byte-range object requests (bytes=0--     1) as invalid. Applications that expect the AWS behavior for negative or other invalid range requests saw     unexpected errors and could fail. With this update, a new option rgw_ignore_get_invalid_range has been     added to RGW. When rgw_ignore_get_invalid_range is set to true, the RGW behavior for invalid range     requests is backwards compatible with AWS.

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870)

CVE-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, caused by a lack of block group item validation in check_leaf_item (bsc#1102896).

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016)

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the versions of the kernel packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the     group key handshake, allowing an attacker within radio range to replay frames from access points to     clients. (CVE-2017-13080)

  - It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable     to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on     network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph     service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable. (CVE-2018-1128)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that received fragments be cleared from memory after (re)connecting to a     network. Under the right circumstances, when another device sends fragmented frames encrypted using WEP,     CCMP, or GCMP, this can be abused to inject arbitrary network packets and/or exfiltrate user data.
    (CVE-2020-24586)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that all fragments of a frame are encrypted under the same key. An adversary     can abuse this to decrypt selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP encryption key is periodically renewed. (CVE-2020-24587)

  - The 802.11 standard that underpins Wi-Fi Protected Access (WPA, WPA2, and WPA3) and Wired Equivalent     Privacy (WEP) doesn't require that the A-MSDU flag in the plaintext QoS header field is authenticated.
    Against devices that support receiving non-SSP A-MSDU frames (which is mandatory as part of 802.11n), an     adversary can abuse this to inject arbitrary network packets. (CVE-2020-24588)

  - An issue was discovered in the kernel in NetBSD 7.1. An Access Point (AP) forwards EAPOL frames to other     clients even though the sender has not yet successfully authenticated to the AP. This might be abused in     projected Wi-Fi networks to launch denial-of-service attacks against connected clients and makes it easier     to exploit other vulnerabilities in connected clients. (CVE-2020-26139)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The WEP, WPA, WPA2, and     WPA3 implementations accept plaintext frames in a protected Wi-Fi network. An adversary can abuse this to     inject arbitrary data frames independent of the network configuration. (CVE-2020-26140)

  - An issue was discovered in the ALFA Windows 10 driver 6.1316.1209 for AWUS036H. The Wi-Fi implementation     does not verify the Message Integrity Check (authenticity) of fragmented TKIP frames. An adversary can     abuse this to inject and possibly decrypt packets in WPA or WPA2 networks that support the TKIP data-     confidentiality protocol. (CVE-2020-26141)

  - An issue was discovered in the kernel in OpenBSD 6.6. The WEP, WPA, WPA2, and WPA3 implementations treat     fragmented frames as full frames. An adversary can abuse this to inject arbitrary network packets,     independent of the network configuration. (CVE-2020-26142)

  - An issue was discovered in the ALFA Windows 10 driver 1030.36.604 for AWUS036ACH. The WEP, WPA, WPA2, and     WPA3 implementations accept fragmented plaintext frames in a protected Wi-Fi network. An adversary can     abuse this to inject arbitrary data frames independent of the network configuration. (CVE-2020-26143)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept plaintext A-MSDU frames as long as the first 8 bytes correspond to a valid RFC1042     (i.e., LLC/SNAP) header for EAPOL. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26144)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WEP, WPA, WPA2, and WPA3     implementations accept second (or subsequent) broadcast fragments even when sent in plaintext and process     them as full unfragmented frames. An adversary can abuse this to inject arbitrary network packets     independent of the network configuration. (CVE-2020-26145)

  - An issue was discovered on Samsung Galaxy S3 i9305 4.4.4 devices. The WPA, WPA2, and WPA3 implementations     reassemble fragments with non-consecutive packet numbers. An adversary can abuse this to exfiltrate     selected fragments. This vulnerability is exploitable when another device sends fragmented frames and the     WEP, CCMP, or GCMP data-confidentiality protocol is used. Note that WEP is vulnerable to this attack by     design. (CVE-2020-26146)

  - An issue was discovered in the Linux kernel 5.8.9. The WEP, WPA, WPA2, and WPA3 implementations reassemble     fragments even though some of them were sent in plaintext. This vulnerability can be abused to inject     packets and/or exfiltrate selected fragments when another device sends fragmented frames and the WEP,     CCMP, or GCMP data-confidentiality protocol is used. (CVE-2020-26147)

  - A flaw was found in the Linux kernel's implementation of MIDI, where an attacker with a local account and     the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to     this specific memory while freed and before use causes the flow of execution to change and possibly allow     for memory corruption or privilege escalation. The highest threat from this vulnerability is to     confidentiality, integrity, as well as system availability. (CVE-2020-27786)

  - In unix_scm_to_skb of af_unix.c, there is a possible use after free bug due to a race condition. This     could lead to local escalation of privilege with System execution privileges needed. User interaction is     not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-196926917References:
    Upstream kernel (CVE-2021-0920)

  - A race condition accessing file object in the Linux kernel OverlayFS subsystem was found in the way users     do rename in specific way with OverlayFS. A local user could use this flaw to crash the system.
    (CVE-2021-20321)

  - An information disclosure vulnerability exists in the ARM SIGPAGE functionality of Linux Kernel v5.4.66     and v5.4.54. The latest version (5.11-rc4) seems to still be vulnerable. A userland application can read     the contents of the sigpage, which can leak kernel memory contents. An attacker can read a process's     memory at a specific offset to trigger this vulnerability. This was fixed in kernel releases: 4.14.222     4.19.177 5.4.99 5.10.17 5.11 (CVE-2021-21781)

  - An issue was discovered in the Linux kernel before 5.11.3 when a webcam device exists. video_usercopy in     drivers/media/v4l2-core/v4l2-ioctl.c has a memory leak for large arguments, aka CID-fb18802a338b.
    (CVE-2021-30002)

  - Improper input validation in the Intel(R) Ethernet ixgbe driver for Linux before version 3.17.3 may allow     an authenticated user to potentially enable denial of service via local access. (CVE-2021-33098)

  - A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on     inbound SCTP packets may allow the kernel to read uninitialized memory. (CVE-2021-3655)

  - A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was     found in the way user uses trace ring buffer in a specific way. Only privileged local users (with     CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service.
    (CVE-2021-3679)

  - hso_free_net_device in drivers/net/usb/hso.c in the Linux kernel through 5.13.4 calls unregister_netdev     without checking for the NETREG_REGISTERED state, leading to a use-after-free and a double free.
    (CVE-2021-37159)

  - A use-after-free flaw was found in the Linux kernel's Bluetooth subsystem in the way user calls connect to     the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the     system or escalate their privileges. The highest threat from this vulnerability is to confidentiality,     integrity, as well as system availability. (CVE-2021-3752)

  - A flaw was found in the Linux SCTP stack. A blind attacker may be able to kill an existing SCTP     association through invalid chunks if the attacker knows the IP-addresses and port numbers being used and     the attacker can send packets with spoofed IP addresses. (CVE-2021-3772)

  - ** DISPUTED ** In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss     can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE:
    the vendor indicates that the cited data corruption is not a vulnerability in any existing use case; the     length validation was added solely for robustness in the face of anomalous host OS behavior.
    (CVE-2021-38160)

  - net/netfilter/nf_conntrack_standalone.c in the Linux kernel before 5.12.2 allows observation of changes in     any net namespace because these changes are leaked into all other net namespaces. This is related to the     NF_SYSCTL_CT_MAX, NF_SYSCTL_CT_EXPECT_MAX, and NF_SYSCTL_CT_BUCKETS sysctls. (CVE-2021-38209)

  - A memory leak flaw in the Linux kernel's hugetlbfs memory usage was found in the way the user maps some     regions of memory twice using shmget() which are aligned to PUD alignment with the fault of some of the     memory pages. A local user could use this flaw to get unauthorized access to some data. (CVE-2021-4002)

  - A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket     file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race     condition. This flaw allows a local user to crash the system or escalate their privileges on the system.
    This flaw affects Linux kernel versions prior to 5.16-rc4. (CVE-2021-4083)

  - A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an     improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of     service (DOS) due to a deadlock problem. (CVE-2021-4149)

  - An out of memory bounds write flaw (1 or 2 bytes of memory) in the Linux kernel NFS subsystem was found in     the way users use mirroring (replication of files with NFS). A user, having access to the NFS mount, could     potentially use this flaw to crash the system or escalate privileges on the system. (CVE-2021-4157)

  - An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces     subsystem was found in the way users have access to some less privileged process that are controlled by     cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of     control groups. A local user could use this flaw to crash the system or escalate their privileges on the     system. (CVE-2021-4197)

  - In the Linux kernel through 5.15.2, mwifiex_usb_recv in drivers/net/wireless/marvell/mwifiex/usb.c allows     an attacker (who can connect a crafted USB device) to cause a denial of service (skb_over_panic).
    (CVE-2021-43976)

  - In gc_data_segment in fs/f2fs/gc.c in the Linux kernel before 5.16.3, special files are not considered,     leading to a move_data_page NULL pointer dereference. (CVE-2021-44879)

  - In __f2fs_setxattr in fs/f2fs/xattr.c in the Linux kernel through 5.15.11, there is an out-of-bounds     memory access when an inode has an invalid last xattr entry. (CVE-2021-45469)

  - In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information     leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based     attackers can typically choose among many IPv6 source addresses. (CVE-2021-45485)

  - In the IPv4 implementation in the Linux kernel before 5.12.4, net/ipv4/route.c has an information leak     because the hash table is very small. (CVE-2021-45486)

  - A vulnerability was found in the Linux kernel's cgroup_release_agent_write in the     kernel/cgroup/cgroup-v1.c function. This flaw, under certain circumstances, allows the use of the cgroups     v1 release_agent feature to escalate privileges and bypass the namespace isolation unexpectedly.
    (CVE-2022-0492)

  - A flaw null pointer dereference in the Linux kernel UDF file system functionality was found in the way     user triggers udf_file_write_iter function for the malicious UDF image. A local user could use this flaw     to crash the system. Actual from Linux kernel 4.2-rc1 till 5.17-rc2. (CVE-2022-0617)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)
